The following table summarizes the best available values of the density, specific heat capactiy at constant pressure (Cp), vapor pressure, viscosity, dielectric constant, and surface tension for liquid water in the range 0-100 °C. All values (except vapor pressure) refer to a pressure of 100 kPa (1 bar). The temperature scale is IPTS-68.
